AMD Releases Threadripper Pro Workstation CPUs to the DIY Market

Remember AMD's Threadripper Pro CPUs which went on sale in prebuilt workstations? Well, they're now available for the general public in boxed CPU offerings - if you have the cash for them. The platform offers support for up to 2 TB of DRAM through its eight-channel configuration, 128 lanes of PCIe 4.0 connectivity, and up to 64 cores (128 Threads with the company's Simultaneous Multi Threading [SMT] technology). The best motherboards for these productivity beasts are, according to AMD, WRX80-based motherboards, which start at a pretty negligible $999.

The company's lineup tops out at the flagship Threadripper PRO 3995WX, which is a 64-core/128-thread max-out of the "Rome" MCM, with a max boost frequency of 4.20 GHz ($5,489). Next up is the Threadripper PRO 3975WX, which is a 32-core/64-thread part, clocked up to 4.20 GHz boost ($2,749). Following this, is the Threadripper PRO 3955WX, a 16-core/32-thread part clocked up to 4.30 GHz boost ($1,149). The Threadripper PRO 3945WX, a 12-core/24-thread part clocked up to 4.30 GHz boost, is apparently absent from this release. If you need the current best from AMD apart from their EPYC CPUs, it doesn't get much better than this.

I see you've mastered the art of understatements.

It would seem these CPUs work with TRX40. That could be an interesting proposition.

So you mean it's outrageously negligible? :p

$1000 for a board of that quality in terms of construction makes more sense than an Z590 or X570 (even TRX40) board in the same price range. Especially if that 12 core is like $800 US.

What I don't like about his board is the lack of PCIe spacing.
You clearly need PCIe Risers to effectively use a board like that.

I don't see a problem with it. VM's with a bunch of single slot cards or a single workstation with a few dual slot cards or a a mix of either and/or NVME cards. All professional workstation video cards are dual slot or smaller.

Or use single slot Expansion cards and put single slot Water blocks on every GPU. I don't even think my HX1200I would be able to run this beast full throttle. F me 2 1600 or 3 1200 Watt PSUs would be needed to run it fully populated anyway.

I totally get that but with something like this you could have workstation and Gaming GPUs on the board. This could probably run a VR arcade all by itself.

I think it'll be more around $1000 $950ish.
The 16 core is listed currently on Newegg U.S for $1150

The prices are fine for the target market for these products they will pay it.

At this price i will just go for EPYC

It ain't like you can put any spacing there anyways. Just a bunch of single-slot cards and tons of active cooling should do, especially if it's a production workstation or multi-user VM/RDS server.
Heck, with those specs maxed out you can stick some relatively affordable Quadro RTX cards in it (apparently NVidia has vGPU licensing for those as GRID/Tesla) and run a huge team of devs, or even bigger team of generic office workers off a single WS.... or just be a total douchebag and run the worlds most expensive ETH mining farm with 7 watercooled RTX3090s :D

EPYC has much lower clockspeeds. So these Threadripper Pros are in fact, superior to EPYC for workstation purposes (which have a variety of single-threaded bound tasks, which need GHz instead of cores).

That's the thing about workstations: they need to be both a client device with high GHz (UI-threads, plugins, etc. etc. are usually single-threaded) AND a... well... workstation with tons of cores for Rendering / whatever.

Your fancy Raytracer might be well-parallelized and utilize 128-threads nice and well. But random custom-loader that was written by Intern #15 that loads/saves the level data in some XML / JSON abomination is going to be single-threaded bound and probably written (poorly) in Python. I mean, ycombinator / Hacker News completely blew up a few days ago when a single-threaded "sscanf" performance issue was tracked down as the reason why GTAV levels took so damn long to load (news.ycombinator.com/item?id=26296339)

That is not my field of expertise. In my bioinformatics field the only reason we previously invested in TR platform was the relatively low entry cost to massive core count CPUs. With this PRO lineup pricing, makes no economy sense to built TR station anymore. University has purchasing discounts for EPYC a lot cheaper even compared to these TR PROs. Might as well just rack it up into the local HPC and dont even have to dust it.

On the other hand, if there are institutional discount for TR PRO, it will be a completely different story XD

It looks like its power requirements are.. demanding..

You can tell its built for pros by its lack of RGB.. all work and no play yawn.

:laugh:

Isn't every CPU RGB free? ;)

Ah right. I think you post about your projects around here sometimes, now that I remember it.

Yeah, EPYC is probably better for your use case. Threadripper Pro seems like it should be more expensive than single-socket EPYC. Dual-socket EPYC might still be more expensive.

I know! You should have seen what I originally wrote but didn't post.. but it involved many chiplets at the end :sleep:

Thank God it says "Built for pros" - I was worried I might need to buy it but since I'm not a pros my wallet should be safe.
